Title: Improvements relating to statistical record controlled machines
IPC: G06V30/224
Filed: 1954-03-29
Abstract: 752,130. Photo-electric record sensing apparatus. GOLDSTERN, N. March 29, 1954, No. 9163/54. Class 40 (3). [Also in Group XIX] A statistical record-card machine is controlled by record cards, Fig. 1, perforated with a number of uniform holes in patterns which may be easily read visibly as numerals or letters, and in which the number of holes is different in each case so that a photo-electric card-sensing arrangement as shown in Fig. 2 may evaluate each different character on the card 3 according to the amount of light passed to the photoelectric cell 5 from the light source. The varying amount of light falling on the cell 5 according to the number of holes contained in each character varies the voltage or current output of the cell accordingly and causes selective operation of one of a number of relays 7. The relay operated presses down the key of machine 8 corresponding to the figure concerned. The input of the amplifier is constituted by the grid-cathode of an amplifier tube, the output of which comprises a condenser shunted by a resistor. In the arrangement shown in Fig. 3 the condenser is connected with the control electrodes of an electronic switch which may be embodied in an electron-beam tube 9. The electron beam 10 is arranged to move over a set of contacts 11, 12, each of which is connected with a relay. The operating circuit of each relay is closed by the electron beam focused on the contact associated therewith.

Title: Process for the production of high molecular quaternary ammonium compounds
Filed: 1937-03-31
Abstract: High molecular water-soluble quaternary ammonium compounds are manufactured by reacting volatile tertiary bases with the products of the action of formaldehyde or its polymers and hydrogen halides or halogens on nitrogen-containing derivatives of saturated fatty acids containing at least ten carbon atoms in the molecule or on urethanes of saturated fatty alcohols containing at least ten carbon atoms in the molecule.  Suitable fatty acid derivatives are higher fatty acid amides or their methylol compounds, higher hydroxamic acids, higher hydrazides, higher amidines or urea or dimethylolurea derivatives acylated on one side with higher fatty acids.  When the initial material is a methylol compound, the use of formaldehyde or its polymers may be dispensed with.  The products are suitable for rendering textiles permanently water-repellent.  In examples: (1) and (3) hydrogen chloride is passed into a warm mixture of stearic acid amide, trioxymethylene and benzene, and the resulting chloromethyl compound is stirred with pyridine; (2) montanic acid amide is similarly treated; (4) stearic acid methylolamide is similarly treated; (5) the reaction of (4) is carried out without the presence of trioxymethylene; (6) stearohydroxamic acid is treated as in (1). Samples have been furnished under Sect. 2 (5) of products obtained by a process analogous to that of example (1) above from (I) stearoylurea; (II) carbamic acid octadecyl ester; (IV) stearic acid hydrazide; (V) octadecanamidine; and of (III) the product obtained by reacting trimethylamine with the N-chloromethylcarbamic acid octadecyl ester obtained as an intermediate in the production of (II).

Title: Textile treatment process
Inventor: WATSON THOMAS
IPC: D06P5/20
Filed: 1959-03-17
Abstract: Cellulose textile materials are impregnated with an aqueous solution of a compound having an atom or group capable of reacting with the hydroxyl groups of the cellulose to form a chemical bond, the moist materials then being placed in contact with a pair of electrodes and subjected to the influence of an electric current in the presence of an electrolyte, an acid-binding agent thereby being generated from the electrolyte and facilitating reaction of the compound with the cellulose.  Specified compounds are dyestuffs of the nitro, azo, anthraquinone or phthalocyanine series, such as those described in Specifications 209,723, 298,494, 460,224, 733,471, 740,533, 772,030, 774,925, 775,308, 780,591, 781,930, 785,120, 785,222, 802,198 and 805,562, dyestuff intermediates such as azoic components, mordants for basic dyestuffs, optical bleaching agents and agents for facilitating the bonding of starches to cellulose textiles for stiffening purposes.  Specified electrolytes are the lithium, sodium, potassium, alkylated ammonium, magnesium, calcium, strontium or barium salts of various organic and inorganic acids.  Direct or alternating current is applied from a pair of rollers, plates or belts as electrodes at a potential difference of, for example, 2-50 volts.  The aqueous solution may be applied by padding or printing and pattern effects may also be obtained by applying the electric current locally to the material, for example, by using engraved or embossed rollers as the electrodes.

Title: Torsion balance for the determination of small variations in the apparent weight of samples
Inventor: BALTAC MIHAIL ALEXANDRU

Filed: 1959-03-18
Abstract: 878,197. Weighing apparatus. MINISTERAL INDUSTRIEI PETROLULUI SI. CHIMIEI. March 18, 1959, No. 9474/59. Class 143 [Also in Group XXXVI] A torsion balance comprises a moving element provided with a horizontal torsion thread and a float which, when immersed in a liquid whose free surface is at the level of the torsion thread, supports the weight of the moving element. The balance is designed for the measurement of small changes in the effective weight of a load and is described with reference to the measurement of magnetic susceptibility of rock samples. The moving element comprises a pair of balance arms al, a2 connected by a ring b whose centre lies on the common axis of the arms. Suspended at the end of arm a1 is a scale pan which comprises a lower container 26 in which is placed a magnetic sample to be acted on by a magnetic field produced by coil 27, and an upper container 28 in which is placed sufficient non-magnetic ballast to make up the total load to a predetermined value which depends on the float volume and liquid density. The arm a2 carries a movable counterweight 7 and a concave mirror 8 which in conjunction with a scale 9 and lamp 10 indicates the orientation of the moving element. The float 12 is immersed in liquid in the container 18 and is attached to the moving element by means of the threaded rod 15, which may be hollow and whose position is adjustable within a threaded block 16 attached to a frame 11 carried by the ring b. A notched lever 30 which engages the frame 11 to hold it down by the tension in spring 34 provides a locking mechanism which is released by rotation of a cam 37. One end of the torsion thread 13 is attached as shown to the frame 11 at the level of the liquid surface and is colinear with a tensioning thread 14. The other end of the thread 13 is held by a torsion head 22 to which is attached a pointer 23, or a vernier, movable over a scale 24. Before use the balance is adjusted, with the said predetermined total load on the arm a1, so as to bring the centre of gravity of the loaded moving element into coincidence with the metacentre of the float, by suitable adjustment of the position of the counterweight 7 on arm a2, a weight 17 on rod 15, and the depth of the float below block 16. In use the same total load is contained in pans 26 and 28 together and the torsion head is rotated until a zero indication is obtained on scale 9. The subsequent small change in the apparent weight of the load produced by the energization of coil 27 disturbs the position of the moving element which is then returned to the zero position by rotation of the torsion head, the consequent change in the reading on scale 24 indicating the magnitude of the magnetically produced change in effective weight of the load.
